Akasha300 3D Printer for Space technology

The Akasha300 3D Printer, India’s first indigenously developed large scale metal 3D printer, is making headlines following its official unveiling on March 25, 2026. Developed through a collaboration between ISRO and IIT-Madras, the machine is being hailed as a “game-changer” for India’s space manufacturing capabilities , This “Made in India” technology marks a major leap in domestic space manufacturing..

Capacity and Application of Akasha300

1. The printer features a significant build volume of 1x1x1 metres, allowing for the production of large, single piece aerospace components that previously required complex assembly.
2.  By developing this technology domestically, India reduces its reliance on expensive, high end 3D printing imports from Europe and the US, aligning with the Atmanirbhar Bharat mission.
3.  ISRO plans to use the Akasha300 to manufacture critical parts for its next generation launch vehicles (NGLV), including rocket engine combustion chambers, injectors and complex structural brackets..
4.  It uses Laser Powder Bed Fusion (LPBF) technology to print high-strength alloys like Inconel, Titanium and Stainless Steel, which are essential for withstanding the extreme heat and pressure of space flight.
5. The printer can reduce the production cycle of complex engine parts from several months to just a few weeks, significantly accelerating mission timelines for projects like Gaganyaan.
6.  The technology enables “topology optimisation “ creating parts that are up to 30-40% lighter without sacrificing strength, which is vital for increasing satellite payload capacity.

Strategic Impact of Using Aakasha300

1. It allows for “topology optimisation ” creating parts that are lighter yet stronger, which is crucial for increasing satellite payload capacity and weight efficiancy
2. The Akasha300 can reduce the manufacturing time of critical engine components from months to just a few weeks due to 3D printing quality
3. By localising production, it significantly lowers the cost of hardware for missions like Gaganyaan and future moon explorations ..

The launch of Akasha300 aligns with India’s goal to become a global hub for cost effective space tech. ISRO plans to deploy these printers to manufacture combustion chambers, injectors and structural brackets for its next generation launch vehicles..
